Therefore, these products with defined 5' and 3' ends accumulate exponentially with each round of DNA amplification -- that is, for every n cycles of PCR there will be 2 -fold amplification of the specific DNA fragment.
1 By themselves, PVCâs do not present any problem.  Bigeminy, Trigeminy, Quadrigeminy, etc. - ventricular bigeminy is the occurrence of a PVC every other beat, trigeminy is every third beat, quadrigeminy every fourth beat.
